Social context is a vital component of Human-Computer Interaction (HCI) design for security; however, there is little discussion about how to provide security functions based on the social context. This study examines the fit between security design and social contexts in mobile payment applications by investigating preferences and perceptions of security design based on the task-technology fit model and the technology acceptance model. To approach the fit of security design in different social contexts, this study followed the approach proposed by design science research and employed a full factorial design experiment. We developed two interfaces—a customizable interface without feedback information and a customizable interface with feedback information—and asked participants to modify security settings in the interfaces according to social contexts, conduct payment transactions, and report their perceptions of security and usability in four payment scenarios. The observed behaviors in relation to security settings and perceptions revealed the fit for security settings and feedback design in different social contexts. Implications were provided to allow insights for security design in mobile payment transactions according to social contexts.

社会环境是人机交互 (HCI) 安全设计的重要组成部分；然而，关于如何根据社会背景提供安全功能的讨论很少。本研究通过基于任务-技术适合模型和技术接受模型调查安全设计的偏好和感知，检验移动支付应用程序中安全设计与社会环境之间的适合性。为了探讨安全设计在不同社会背景下的契合度，本研究沿用了设计科学研究提出的方法，并采用了全因子设计实验。我们开发了两个界面——一个不带反馈信息的可定制界面和一个带反馈信息的可定制界面——并要求参与者根据社会背景修改界面中的安全设置，进行支付交易，并在四种支付场景中报告他们对安全性和可用性的看法. 观察到的与安全设置和感知相关的行为揭示了安全设置和反馈设计在不同社会环境中的适用性。提供的含义是为了根据社会背景深入了解移动支付交易中的安全设计。观察到的与安全设置和感知相关的行为揭示了安全设置和反馈设计在不同社会环境中的适用性。提供的含义是为了根据社会背景深入了解移动支付交易中的安全设计。观察到的与安全设置和感知相关的行为揭示了安全设置和反馈设计在不同社会环境中的适用性。提供的含义是为了根据社会背景深入了解移动支付交易中的安全设计。
